鸭子也被叫做水鸟,常在湖边,河边以及池塘边出现。 [1] X 研究来源 有些种类的鸭子很容易区分公母,但是有些种类的公母区别就不是很明显了。不过,一旦你知道应该观察什么,很快就可以区分出公鸭和母鸭。
步骤
-
另外一种区分鸭子公母的方法就是把鸭子放在桌子上,检查它的泄殖腔。 这种方法适用于单一形态的鸭子,也就是公母的外部特征相同,也可以用来分辨才12天大的幼鸭。 [21] X 研究来源 这种方法操作起来比较困难,如果你不想自己操作,可以请更有经验的人来帮你。 [22] X 研究来源
- 把鸭子放在桌子上时,将它的胸口朝上面对你,腿部朝下。然后把鸭子的尾部悬在桌子边缘,这样你才能让它弯下来,检查它的泄殖腔。 [23] X 可靠来源 Food and Agricultural Organization of the United Nations 前往来源 [24] X 研究来源
- 如果你没有一个固定的平面来放鸭子,你也可以跪下来把鸭子放在腿上,这样它的尾部会悬在你的膝盖上,也可以很轻易地弯过去,方便你检查。 [25] X 可靠来源 Food and Agricultural Organization of the United Nations 前往来源
- 检查幼鸭的泄殖腔要比成年鸭困难,最好是请专业人士来检查。
-
将鸭子的泄殖腔壁和生殖器露出来。 用食指把鸭子尾部下边的羽毛往下折,再用中指和无名指把尾部上边的羽毛往上折。把拇指放在泄殖腔两侧慢慢往两边拉,这样就可以把鸭子的泄殖腔壁和生殖器露出来。 [27] X 研究来源
-
辨别泄殖腔里面的生殖器官。 把鸭子的泄殖腔壁和生殖器露出来之后,就可以区分它的公母了。如果有阴茎从泄殖腔里面伸出来,那这就是公鸭。 [29] X 研究来源 如果泄殖腔里面有输卵管开口,那就是母鸭。 [30] X 研究来源
- 年幼公鸭的阴茎很小,暴露在外面;成年鸭的阴茎很大,隐藏在泄殖腔里面。 [31] X 研究来源
